[PATCH] s390: deadlock in appldata The system might hang when using appldata_mem with high I/O traffic and a large number of devices. The spinlocks bdev_lock and swaplock are acquired via calls to si_meminfo() and si_swapinfo() from a tasklet, i.e. interrupt context, which can lead to a deadlock. Replace tasklet with work queue.
